134 ARANEIDEA. 
The sternum is oval, truncated at the fore end. 
The abdomen is moderately large, of a somewhat triangular form, with astrong obtusely pointed subconical 
eminence at each of the fore corners. Its colour is dull luteous, spotted irregularly with white ; 
between each of the eminences and the spinners is a distinct black spot, and there are several others, 
smaller and round, just above the spinners. Probably some variety would be found in a series of examples 
in respect to the abdominal pattern or markings. 
Hab. Mexico, Teapa in Tabasco (#. H. Smith). 
EPEIROTYPUS, gen. nov. (Theridiide). 
Cephalothorax distinctly longer than broad; lateral marginal indentation strong, and the margins furrowed or 
impressed. Caput drawn out forwards, and the indentations dividing it from the thorax strong. Clypeus 
low, not exceeding in height the diameter of one of the fore-central eyes. 
Eyes large, subequal, occupying the whole width of the fore part of the caput. The hind-centrals form a line 
rather longer than the fore-centrals; they are separated from each other by more than a diameter’s 
interval, and from the hind-lateral eye on its side by half that space or less. The eyes of the lateral 
pairs are nearly but not quite contiguous, and each of the fore-laterals is nearer to the fore-central next 
to it than the fore-centrals are to each other. 
Legs short, strong, tapering, subequal, 1, 2, 4, 3, furnished with longish hairs and bristles, a few of the latter 
being longer and of a spine-like character. 
Falces straight, moderate in length and strength. 
Maville short, broad, and rather roundly truncate at the apex. 
Labiwm small and somewhat semicircular, a little less than half the length of the maxille. 
Sternum subtriangular ; the posterior extremity obtuse and somewhat drawn out, the anterior hollow-truncate. 
Abdomen large, broadest at the posterior extremity, rounded before, squarely truncate behind, considerably 
elevated but rather flattened on the upperside, and projecting a good deal over the thorax. The genital 
aperture is situated much nearer the middle of the underside of the abdomen than usual, and the 
spiracular openings are also further back than usual. Spinners short, compact, and with the transverse 
lip of a spiracular opening close in front of them. 
Epeirotypus brevipes, sp. n. 
Adult female, length 13 lines. 
Cephalothorax deep yellowish-brown and glossy, with a yellowish marginal line, and a short strong, curved, 
yellow bar on each side of the thoracic indentation, the convexity of the curves directed away from each 
other. The thorax has also several short converging blackish lines on each side. 
The four central eyes form a square, whose anterior side is shorter than the others; those of the posterior row 
form very nearly a straight transverse line; the anterior row greatly curved. 
Legs yellow, rather irregularly annulated with blackish and yellow-brown ; femora of unusual strength. 
Palji short, similar to the legs in colour and armature. 
Falces yellow-brown, marked near their base in front with dusky brown. 
Mawille and labium yellow, suffused with brown at their base. 
Sternum dusky vrown in the middle, with a broad yellow margin. 
Abdomen broad, rather quadrate behind, obtusely rounded in front; the upperside flattened, convex, white, or 
dull-coloured, and closely spotted with white, with a small blackish central spot: at the hinder extremity on 
either side it is somewhat subangularly prominent. The sides and underside are black-brown, obscurely 
mottled with whitish ; the upper margin of the black-brown parts is somewhat denticularly irregular, but 
well-defined above the spinners ; the hinder slope, which is vertical, is marked with alternate transverse, 
short, straight, yellowish and black-brown bars. The genital aperture is very simple, but characteristic, 
and is placed immediately behind a large convexity (which reaches to the fore end of the abdomen), being 
thus nearer to the spinners than to the fore end. The normal spiracular openings are on each side of the 
genital aperture as usual, but are still much further back than is commonly the case. On either side just 
behind the genital aperture are two small, bright, whitish-yellow spots in a transverse line.
